CAR-COUPLING,

Original application filed July 20, 1911, serial No. 639,589.

Specification of Letters Patent.

Serial No. 30,307.

To all whom it may concern:

Be it known that I, ARTHUR J. BAZELEY, a citizen of the United States, residing at Cleveland, Cuyahog-a county, Ohio, have invented new and useful Improvements in Car-Couplings, of which the following is a specification, reference being had to the ac companying drawings, in which Figure 1 shows a vertical section of a coupler embodying my invention, on lines TT of Fig. 51, and with the lock in locked position; Fi 2 is a section similar to Fig. 1 but showing the actuation of the lifter to free the look from the locleto-the-lock; Fig. 3 is a section similar to Fig. 1 but with the lock in lockset position; Fig. 4 is a bottom .plan thereof; and Fig. 5 is a sectionsimilar to Fig. l but with the parts in knucklethrown position. v 1

My invention relates to car couplers of the automatic type, and particularly to the construction and operation of the locking and knuckle-throwing members, and to various other details of construction hereinafter more fully described.

The present application is a division of my pending application, Serial No. 639,585), filed July 20, 1911.

Referring to the drawings, the numeral 2 designates the coupler head of. the general form of the Master Car Builders type, provided with the usual upper and lower jaws 3, between which the knuckle 4L swings. The locking piece 5 has a head of relatively large cross-section, so as to afford large looking surfaces for the knuckle, and a depend ing reduced leg 6, one side of which has a curved face 7 and terminates at its lower end in the forwardly-oflset portion 8, having therethroughan inclined slot-like opening 9, the purpose of which will hereinafter appear. The head of the lock is also formed with a. forward projection 10, having in its upper side an undercut recess -11, which is adapted for engagement with the rearward projection or shoulder 12 on the front wall of the interior of the coupler head.

The knuckle-throwing member 13, in the form of a bell crank lever, rotates on a pin or stud 1 1, depending from its angle, which seats in a bearing in the floor of the coupler cavity. The member 13 has a forwardly-extending arm, preferably provided at its forward end with an upward projection 15, which is adapted to engage the under surface of the knuckle tail. The laterally-extending arm 16 of the member 13 is'adapted to support the locking piece 5 in lockset position by its engagement with the shoulder 17 of said piece, as is shown in Fig. 3.

The lifter 18 consists of'a lever pivoted to the under side of the coupler head, and is formed with an eye 19 for engagement with ing up, as the end 22 of the lifter will come into contact with the projection 21, as is shown in Fig. 1. To move the parts into lockset position, the lifting lever 18 is actuated, which causes the pin 20 to slide up- -wardly and rearwardly in the inclined slot 9 of the leg 6 of the lock 5, so that, when the lifter 18 is raised to a position, as is shown in F ig. 2. in which the pin 20 engages the upper end of the slot 9, its upper end 22 is clear of the shoulder 21 and thereby permits the lifter to raise the lock and move it rearwardly to seat by its shoulder 17 on the arm 16 of the thrower 13. The fulcruming action of the projection 10-of the lock on the shoulder, 12 of the coupler head assists in rendering the lockset seating action more positive. A further lifting movement of the lever 18 will cause a further fulcruming movement of the locking piece on the shoulder 12 and thereby force its depending leg 6 rearwardly against the lateral arm 16 of thethrower 13, so as to cause it to rotate and thereby throw the knuckle into open position. a

It will be seen by particular reference to Fig. 5 that the lower end of the leg 6 of the lock must be tipped rearwardly in order to operate the knuckle-thrower 13. This is ac- The upper complished by thecooperation of the proby the cooperation of the lock lifting mechanism and the leg 6 of the lock. As the lever 18 is raised to li t '18 first travels upwardly, and about the the lock the lever member time the lock reaches lock-set position it begins to tiprearwardly because of the circular path in which the free end of the lever 18 is forced to travel by reason of its pivotal attachment to the coupler head. The levers 18 and 18 have a toggle action so that, as

.any further lifting effort is applied at 19,

the end of the lever 18 which is attached to the lock, will move rearwardly and will force the leg of the lock rearwardly, thereby assisting the fulcru'ming action of the lock on the shoulder 12. v

The upper surface of the knuckle tail is formed with an incline or cam surface 23, and, as the knuckle tail swings forwardly, this cam surface 23 will come into contact with the under side of the projection 10 and raise the locking piece sufficiently to free it from its lock setting engagement with the knuckle-throwing member 13, and cause it to be hung upon and supported by the knuckle tail. As soon as the pressure on the operating lever 18 is relieved, the depending leg 6 on the lock 5 will swing forwardly, sothat in the subsequent closing movement of the knuckle its tail will swing out from under the lock and the latter will drop freely to its locking position.

The terms and expressions which I have employed'are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any mechanical equivalent for the features shown and described, but recognize that various structural modifications are possible within the scope of th invention claimed. 7 I

What I claim is:

1. In a car coupler, a lock having a depending leg, the said lock having a fulcrum bearingon the coupler-head, a lock-lifting lever pivoted to the under side of the cou- 3. In a car coupler, a' lock having a depending leg, a'lever pivoted to the under 'side of the coupler-head to swing rearwardly and upwardly, and a link pivoted to the lever and to the leg of the lock, the said link, upon actuation of said lever, being adapted to swing rearwardly relative to said lever and thereby lift the lock vertically and move its leg rearwardly for lock-setting and knuckle-throwing.

4. In a car coupler, a lock having a depending leg and having on its forward portion a fulcrum bearingadapted, when the lock is lifted, to be brought into fulcruming engagement with the coupler-head, and actuating mechanism secured to the under side of the coupler-head, pivoted to the leg of the lock to the rear of a vertical line passing "through the fulcrum-bearing on the lock,

said actuating mechanism being adapted to lift the lock by its leg into engagement with the head to fulcrum thereon, said lock, on further actuationby said mechanism, being adapted to be swung rearwardly by said mechanism and fulcrum into positive engagement with a knuckle-throwing member.

5. In'a car coupler, a lock having a downwardly-extending leg and having also a fulcrum-bearing on its forward portion, a lifting mechanism for said lock comprising a lever pivoted to the coupler-head forward of the lock-leg and said fulcrum, and a link pivotally connected to said lever and engaging the lock-leg, said link, in its initial locklifting positions, being adapted to lift the lock perpendicularly and at the same time to move' rearwardly, the forward portion of said lock fulcruming on the coupler-head, whereby when the lock is lifted and its leg is tilted rearwardly by said link, the said fulcrum swings the leg of the lock positively to the rear, in engagement with a knucklethrowing member. i
